Beverage sealing cap

Abstract

A beverage sealing cap that absorbs oxygen keeps a bottled beverage, such as a bottle of wine, fresh after opening and re-sealing. The beverage sealing cap is made with a thermoplastic elastomer stopper containing an oxygen absorber. When inserted into an opened beverage bottle, the stopper seals the bottle to prevent ingress of air, while the oxygen absorber removes the oxygen present in the air inside the bottle. As a result, the contents of the bottle are preserved in a fresh state, avoiding degradation of flavor and waste due to spoilage.

What is claimed is: 
     
         1 . A beverage sealing cap, comprising:
 a stopper having an aperture;   an oxygen absorber within the aperture; and   a plug configured to hold the oxygen absorber within the aperture,   wherein the plug is further configured to allow the ingress and egress of air, such that the oxygen absorber removes oxygen from the air in a bottle on which the stopper is placed.
